RAILROAD TIE.

Specification of Letters Patent, .Patented Angl .'15,` 1922.

Application filed October 27, 1920. Serial No. 419,800.

To all whom t may concern:

Be it known that I, THOMAS D. MCCARTY, a citizen of the United States of America, a resident of Hawk Point, in the county of Lincoln'and State of Missouri, have invented certain new and useful Improvements in Railroad Ties, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in railroad ties, one of the objects being to produce a strong and simple railroad tie co1n prising a concrete body provided with resilient rail supporting members, preferably wooden blocks. A. further object is to provide a simple means for reinforcing the con- Y crete body, in combination with rail fastening means whereby the rails and wooden blocks maybe securely attached to the reinforcing means in the concrete.

Fig. I is a top or plan view of a railroad tie embodyingthe features of this invention.

Fig. II is an enlarged longitudinal section of the elements shown in Fig. I, the middle portion of the tie being broken away.

Fig. III is a transverse section taken approximately on the line III-III, Fig.

As an illustration of one form of the invention, I have shown a railroad tie comprising a concrete body A provided with recesses in its top face, andresilient blocks B seated in said recesses, said resilient blocks being preferab-ly made of wood. The blocks and recesses may be equal in width to the concrete body A, and in this event the con 4 crete will be comparatively weak at points directly below the rails l which rest upon the blocks B. f

To reinforce the concrete structure, a pair of longitudinal reinforcing bars 2 is located in the concrete body,vand these bars extend from one end o-f Asaid body to the other end thereof. In the structure I have shown, the top faces of the flat reinforcing bars 2 are Hush with the bottom walls of the recesses in which the resilient blocks B are mounted, and these blocks are seated upon the reinforcing bars as well as upon the concrete forming the bottom Walls of the recesses. l,

The rail fasteners herein shown include vertical bolts 3 extending through the reinforcing bars, and also through the resilient blocks B, each of said bolts having a head 3 anchored in the concrete below one of the f reinforcing bars and a threaded upper end projecting from the topof one of theresilient blocks. 4 designates rail fastening clips mounted on the extended Vupper ends of bolts 3 and overlapping the rails, as shownin the drawings. To secure the clips 4, nuts 5 are screwed onto the upper ends of bolts 3. It will be observed that each resilient block B' is provided with a pair of the attaching bolts 3 and that one of the bolts of this pair is secured to yone 0f the reinforcing bars 2,

while the othervbolt is secured to the other reinforcing bar. t 1

The bolt heads 3 are anchored in the concrete in such a manner that they serve as means for anchoring the lreinforcing bars 2. The vertical bolts 3 also perform the added functions of securing the resilient blocks B to the concrete and at the same time serving as means for connecting the'rail fastening members 4 to the reinforcingfbars 2 in the concrete. The simple reinforcing bars 2 are therefore rmly anchored in the-concrete-' and the rails are securely attached to the reinforcing bars through the medium of the bolts 3, which also serve as means for attaching the resilient blooksto the tie. i

I claim: 'Y Y A railroad tie comprising a concrete body providedwith recesses inits top face, resilient blocks in said recesses, said recesses and resilient `blocks being equal in width to said concrete body, a pair of longitudinal reinforcing bars located in said concrete body and extending from one end of said body to the other end thereof, the top faces of said reinforcing bars being' flush with the bottoni .walls of said recesses to form seats for said t of said pairs of bolts extending through one of said longitudinal reinforcing bars, and

bars Aand alsov the other bolt of each pair of bolts extending through the other of said reinforcing lbars, each of said vertical bolts having a head anchored in the concrete directly below the reinforcing bar and a threaded upper end pro- `je'cting from the top of one of said resilient blocks, and threaded nuts screwed onto the threaded upper ends of said bolts.`

In testimony that I claim thevforegoing I hereunto aHiX my signature.

THOMAS D. MCCARTY.
